Patented May 16, 1916.

Application filed September 7, 1915. Serial No. 49,148,

T 0 all wit Omit may concern: Be it known that I, .JOHN URBaN, a citizenof the United States of America, residing at Detroit, in the county ofWayne and State of Michigan, have invented certain new and usefulImprovements in Molds for (,iarbage-lteceptacles, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

This invention relates to molds for concrete receptacles, and myinvention aims to provide a novel mold by whichconcrete receptacles,such as garbage containers, can be expeditiously and economicallyproduced from concrete or a similar plastic material.

In the production of concrete receptacles having comparatively thickwalls, it is essential that the mold have rigid and durable wallsarticulated in a manner that permits of the walls being easily andquickly sembled and disassembled. With .-this thought in view, thegreater part of the mold is made of metal and novel means is providedfor holding the various walls of the mold in position to withstandstresses and strains during the pouring of concrete and the formation ofreceptacle walls.

My invention further aims to provide a novel mold for producing asanitary garbage receptacle possessing many improvements which permit ofgarbage being easily placed in the receptacle and readily removed fromthe same. The receptacle so produced has water shedding surfaces andprovision is made whereby the receptacle can be easily drained of anyliquid garbage that may accumulate therein.

My invention will be better understood when the construction of the moldhas been considcred,and reference will now be had to the drawings.wherein there is illustrated a preferred embodiment of my invention, butit is to be understood that the structural ele ments are susceptibleto'such changes, in size, shape and manner of assemblage, as fall withinthe scope of the appended claims.

In the drawings, Figure 1 is a longitudinal sectional view of a mold inaccordance with my invention; Fig. 2 is a cross sectional view taken onthe line 1I-II of Fig. 1; Fig. 3 is a horizontal sectional view taken onthe line Ill-IIl of Fig. 1; Fig. 4% is a front elevation of a mold,partly broken away and partly in section; Fig. 5 is a side elevation ofa mold; Fig. 6 is a plan ofa portion of the mold, illustrating a wallconnection of the core of the mold; F ig. 7 is a perspective view of acompleted article, the receptacle portion of which is produced by themold; Fig. 8 is a longitudinal sectional view of the same; Fig. 9 is aplan of a cover mold; Fig. 10 is a longitudinal sectional view taken onthe line XX of Fig.9, and Fig. 11 is a perspective view of the coverproduced by the mold shown in Figs. 9 and l In Figs. 1 and 2, the moldis illustrated in an inverted position, and it is in this position thatconcrete or other plastic material is placed in the mold. The moldnecessarily includes an outer casing and a core, both of which arecollapsible in order that the same may be removed after a receptacle hasbeen formed having a bottom wall, side Wall and front and rear walls.The top of such receptacle is formed by a difierent mold, and referencewill first be had to the outer casing of the mold shown in Figs. 1 to 5inclusive. The outer casing comprises a base plate 1, rectangular inplan, and the bottom side of said base platehas a reinforcing orstiffening frame 2 and transverse Z bars 3,Wlll0l1 serve functionally asfeet for.

the mold, while concrete is being poured into the same. On the baseplate 1 are longitudinal parallel angle bars 3 serving as guides andbraces for the core of the mold. On the rear end of the base plate 1 isa rear wall l, said wall being reinforced and stiffened by a rectangularframe 5 and angle bars 6. The sides of the rectangular frame 5 haveprojecting lugs 7 and pivotally connected to said lugs, as best shown inFig. 2, are latches 8. These latches are adapted to be swung intoengagement with angle bars 9 stiffening and reinforcing said-walls 10.The side Walls 10 rest upon the bottom plate 1, and the forward edges ofsaid side Walls are disposed at an inclination or cut of an angle,whereby an inclined front wall 11 can be placed upon the bottom plate 1against the forward edges of the side walls 10. The inclined front wall11 has a frame 12 and angle bars 13, and said frame supports latches 1 Ladapted to engage the angle bars 9 of the side walls 10. The elements12, 13 and 14; correspond to the elements 5, 6, and 8 of the-rear wall4.. The front accommodate a gate core 17' held in position by a pin 18passing through the core and engaging in the offset portion 15 of thefront wall. The offset portion 15 is adapted to form a rectangularenlargement 19 on the inclined end wall 20 of the concrete receptacleshown in Figs. 7 and 8, and the gate core 17 is adapted to form arectangular opening 21 in the wall 20. This opening is normally closedby a metallic gate 22 connected to the enlargement 19 by hinges 23, andin order that the hinges may be connected to the enlargement 19, theoffset portion 15 is provided with detachable pins 24 adapted to formopenings in the wall 20 whereby the hinges 23 may be connected theretoby bolts and nuts 25 or other fastening means. The gate 22 has atransverse bar 26, and the ends of this bar are connected by coiledretractile springs 27 to the wall 20. To facilitate connecting thesprings to said wall, the front wall 11 is provided with pins 28 adaptedto form openings to accommodate fastening means for said springs. Thesesprings are adapted to retain the gate 22 closed or opened, and saidgate has a suitable handle or bail 29. To facilitate removing the gatecore 17, after the pin 18 is removed, handles 30 on the sides of thegate core are gripped, and to facilitate positioning the front wall 11,the lower edgeof said wall has dowels 31 to engage in openings providedtherefor 1n the base plate 1. The side walls 10 have dowels 10 and theend walls 4 have dowels 4*, all of said dowels extending through cutaway portions of the angle bars 6 and 9 of the walls to engage in thebase plate 1. The side walls 10 are provided with detachable pins 32 and33, the former providingopenings in the side walls 34 of the concretereceptacle, whereby straps 35 may be connected to the outer sides ofsaid wall. The pins 33 provide openings in the same walls to accommodatepivot pins 36, and the purpose of said pins and said straps will behereinafter referred to.

Reference will now be had to the core of the mold, which comprises arear wall 37, side walls composed of sections 38 and 39, a

' front Wall 40 and atop wall 41. The rear,

side and front walls are in spaced relation to the walls of the outercasing in order to form walls of the concrete receptacle, and toproperly space said walls, the lower edges of the front and'rear walls40 and 37 have dowel pins 42 adapted to engage in the base plate 1 ofthe outer casing. These walls also have the lower edges thereof providedwith cleats 43 cotiperating with cleats 44 of the sectional side wallsin providing a seat 45 at the top of the concrete receptacle. See Fig.8. The inner sides of the sectional side walls are provided withstiffening or reinforcing angle bars 45 against which the walls 37 and40 rest. These angle bars are engaged by pivoted latches 46,

carried by the walls 37 and 40, and the angle bars of each wall areconnected by a cross bar 47 pivotally supported by one angle bar andextending across to the other angle bar where it has a pivoted latch 48engaging a keeper 49 on said angle bar. This construction is best shownin Fig. 2. The lower ends of the angle bars 45 engage the center sidesof the angle bars 3 at the ends thereof and cooperate with the dowelpins 42 in correctly positioning the core. The sections 38 and 39 of theside walls have abutting beveled cleats 50 and 51 and the former areprovided with pivoted latches 52 adapted to engage in keepers 53 carriedby the cleats 51. These abutting beveled cleats are carried by the innersides of the sections 38 and 39, and it is necessary to make each ofthese side walls of two sections, whereby the Wall sections may beshifted inwardly and the core easily disassembled. The sections 39 ofthe side walls have the upper edges thereof beveled to support a beveledportion 54 of the top plate 41, said top plate having flanged edges toengage the upper edges of the walls 37 and 40. The bottom side of thetop plate 41 has resilient positioning clips 55 adapted to engage theinner sides of the sectional side-walls and the walls 37- and 40. Theangularly disposed portion 54 of the top plate 41 is provided with' anopening 56 to accommodate a tube 57 extending through the inclined frontwall of the outer casing, as best shown in Fig. 1. The tube 56 mayremain in the I front wall 20 of the concrete receptacle, as best shownin Fig. 8, and provide a drain for liguid garbage that may accumulatewithin the receptacle. The outer end of the tube 57 may be closed by astopper 58.

Reference Will now the had to the formation of a cover 59 adapted to beplaced upon the seat 45 of the concrete receptacle to close the top ofthe same, said cover being cemented or otherwise secured in position. Toform this cover a mold board 60 is employed, said mold board having thetop thereof provided with inclined faces 61. At the outer edges of thefaces 61 are openings 62 for dowel pins 63 carried by outer retainingwalls 64 mounted upon the mold board. The retaining walls 64 areconnected together similar to the walls of the outer casing of the mold,that is, by pivoted latches 65 engaging angle bars 66, as best shown inFigs. 9 and 10. At the inner edges of the inclined faces 61 are openingsfor dowel pins 67 positioning a rectangular frame 68, said frame havinghandles 69 whereby it may be easily moved. Adjacent to the frame 68 areopenings 70 in the mold board 60 to accommodate sets of pins 71 adaptedto produce vopenings 72 in the molded cover 59, as best shown in Fig.11. The openings 72 permit of hinges 73 being meas y.

connected to the cover to accommodate a metallic lid 74. Connected tothe metallic lid Tl is a transverse strap 75 having depending endspivotally connected, as at '76, to links 77 extending through the straps35. The lower ends of the links 77. are pivotally connected to bars 78fulcrum-ed upon the pivot pins 36. The bars 78 are connected by astirrup 7 9 and by depressing the stirrup 79, the lid H is automaticallyopened, thereby allowing a person to easily place garbage in thereceptacle through the opening 80 formed in the cover 59.

With the core properly assembled within the outer casing and all of thepins in position, clamping bars 81 are placed longitudinally of the topof the outer casing, said bars being connected by a plate 82. The endsof the clamping bars 81 are slotted to receive the threaded ends 83 oftie bars 84, said tie bars having hook shaped ends 85 to engage underthe marginal edges of the base plate 1, as best shown in Fig. 1. The tiebars 84 at each end of the mold are 'connected by end plates 86 providedwith trunnions 87, and said tie bars are retained in engagement with theclamping bars 81 by winged thumb nuts 88 screwed upon the threaded endsof said bars. l Vith all of the elements thus assembled, concrete can bepoured into the outer casing and if neces sary tamped therein. After theouter casing is filled with concrete, the concrete is leveled off flushwith the upper edges of the walls of the outer casing. The concrete isthen allowed to solidify and season if necessary, and to facilitateinverting the mold, a pair of horses or end bearings 89 may be employedto support the trunnions 87 and hold the mold in an elevated position,as shown in Fig. After the concrete has solidified, the mold can beinverted, suitable blocks placed under the same, the tie bars 84 removedand then the outer casing and core disassembled. The concrete receptacleformed in this manner can be advantageously located in an opening of afence or wall, with the greater portion of the receptacle at the innerside of the fence, whereby the lid '74 can be opened and garbage placedtherein. The gate 22 will be on the outside of the fence and by openingsaid gate, a shovel can be inserted in the receptacle to remove garbage.been disposed at an acute angle relative to the bottom of the receptacleto prevent garbage from passing through said opening, particularlyliquid garbage, and in order that such garbage will settle to the bottomof the receptacle, the angularly disposed portion 54 of the top plate 41of the core produces an inclined wall 90 at the inner end of the gateopening 21.
